Flexible 'slinkies' form in DNA of archaea

New cryo-electron microscopy images suggest archaeal microbes pack their chromatin into tight coils that can spring open, forming unexpected contortions.

Modern microbes provide window into ancient ocean

Step into your new, microscopic time machine. Scientists at the University of Colorado Boulder have discovered that a type of single-celled organism living in modern-day oceans may have a lot in common with life forms that ...

Structure of the enzyme behind the world's smallest turbine, solved

The chemical ATP, adenosine triphosphate, is the fuel that powers all life. Despite ATP's central role, the structure of the enzyme generating ATP, F1Fo-ATP synthase, in mammals, including humans, has not been determined. ...

Earth's species have more in common than previously believed
